Released as part of the 2015 'Polka Dot' collection alongside the Nike Internationalist and Air Max 1, the Nike Air Max 90 LTR Premium 'Polka Dot' features a cotton upper adorned with polka dot patterns and a subtle black mudguard that partially conceals the tonal Swoosh. Standout elements of this shoe include a vibrant contrast liner, a leather tongue, and textured rubber overlays on the eyestays and heel branding. These same materials are also used on the midsole, which encases the visible Air unit in the rear.
